Costly production stoppages in municipal heating plants are a common problem across the country. Right now, a municipality in central Sweden is the first to try the technical solution that addresses the problem caused by aluminum packaging in the waste.
When the aluminum, which reaches the CHP plant via the garbage truck, is fired in the boiler, it melts and flows into the air holes where it solidifies. This means that the entire boiler has to be shut down and the metal has to be removed by hand. Such a breakdown can happen several times in a year, costing millions each time. With Our 's technical solution for separating aluminum from, for example, waste wood, it is now possible to both avoid production stoppages and to recycle more of the energy-intensive metal.
By adding a powerful eddy current magnet and adapting Norditek's flexible plant to the material flow, all incoming material can be separated and recycled more efficiently. The technology enables metal recycling of small particles of non-magnetic metal (such as aluminum).
Great benefit at the community level
There are over 300 heating plants in Sweden today, many of which have the same problems, which means that the social cost of the loss of production is hundreds of millions. It also means that the amount of aluminum that can be recycled has a significant impact on the recycling rate of aluminum in Sweden. This recycling saves 95% of the energy otherwise needed to create new aluminum.
It's not just about aluminum
The problem also arises with waste coming from the construction side, where there may be brass and other metals that present the same challenge to manage.
The advantage of Norditek's flexbila plant is that it is easily adapted to new material flows. If the next batch of waste coming in contains a different metal, plastic or material size, the modular plant can easily be adapted, expanded and optimized for the new flow.
More benefits of the technology
With the help of screen, wind screens and water bath , Norditek's facilities make it possible to achieve very far-reaching and efficient recycling of different types of waste.
The advantage is not only an increased recycling rate, but also reduced transportation and reduced mining operations. Last but not least, it also gives the material owner increased revenues with higher revenues on all end products.
